Inequality in Workplace Conditions and Health Outcomes

This paper examines the relationship between the inequality in workplace conditions and health-related outcomes in Japan. It analyzes the effect of changes in the work conditions and work arrangements on the subjective health, activity restriction, and depression symptoms, using the Japanese Life Course Panel Survey (JLPS). The 2007 JLPS consists of nationally representative sample of the youth (20 to 34 yr old) and the middle-aged (35 to 40 yr old). The original respondents were followed up in 2008, and 2,719 respondents for the youth panel and 1,246 for the middle-aged panel returned the questionnaires. The first major conclusion is that there are substantial changes in health conditions between the two waves even though the distributions of health-related outcomes are very similar at two time points. The second major conclusion is that the effects of work conditions depend on different health-related outcomes. Self-reported health and depression symptoms are affected by a variety of job-related factors. The atmosphere of helping each other and the control over the pace of work are two important factors which affect both depression and self-reported health. All these findings suggest that the workplace conditions and job characteristics have profound influence on the workers' health.
